Application.;. fi1ed: 0ntoher;18; 19121 Santana-7263760. Renewed October1;, 1913: se1lia1 Rnn798,8Y-5h To all'whoin t'mayconcems'-:

Be itknown-that 1;; FRAN'IG' Mossenno, acitizenof the United States,residingat Attleboro, in the-countyof Bristol -and State ofMassachusetts, have invented certain new and useful'Improvements in--Wrenches,- of which the following is, a-specificatiom v My invention.relates to ratchet-wrenches and has for its primary objects the-proviesion of a body capable oficonstructionatfa minimum expense, andadapted'to inc-lose the operative parts to make it possibleto reverse the.direction of travel, of the ratchet head; and to provide a reversalmechanism convenient to operate,

The invention accordingly consists in the features of' construction,combinations of elements, and arrangement of-partswhich will beeXemplifi'edin-th'e construction here inafter set forth; andthe. scopeof 'the ap} plication of which will be indicated-inthe appended claims.

In, the accompanying; drawings which form a part of'thisspec'ification,--Figures l and 2 are front and side. elevationsrespectively of a ratchet wrench embodyingmy invention, part of thehandlebeing broken away, Fig. 3, a view similar to that-ofFigt 1, butshowing -aportion of; the: front plate broken away, Figs. l, 5 and 6,sections on lines w w, w a" and y y respectively ofFig. 1, and Fig. 7, asection on line a z of Fig. 3.-

Like reference characters indicate like parts throughout the views.

My wrench is composed of a broad tapering head portion A and a narrowhandle portion B, the whole consisting of a front plate C and a backplate D similar to each other in all respects, provided respectivelywith inwardly directed marginal flange portions 0 and a; transverselydisposed depressed portions in the head, d and d; and longitudinallydisposed depressed portions, 6 and e, in the handle. The plates C and Dare also provided in their head portions respectively with circularopenings f and f adjacent rectangular perforations g and g; transverseopenings h and h in the transverse depressions; and perforations 7c andlo respectively in the handle portion. In the head portion of saidplates are respectively provided perforations Z and Z to receive rivetsm. Rivets a in perforations 7c and 70 also assist the first mentionedrivets in holding the edges of the flanges 0 and 0 in contact; 'and thecombined plates- Will be seen to hie-hollowand-'form-a completehousplates -G and D Y are made of" comparatively thin metal capableofbeingbentf or de-' pressed with comparative ease withsuitable tools,thusavoidingythe expense-of material, ,labor infinishing, jand excessiveweight inherent inwrenches 'whose" bodies are of solid material Acylindrical-ratchet head or body 0 is provided with a central angularopening 0, andan annular series of peripheral teeth 0 midway its frontand rear faces. This head turns loosely in the openings f, f of thehead'portion A andis secure. against de:

taehment by the sidefaces of the teeth'which slidablybearz'against..t-he inner faces of" the front-and 'back pl'ates'G andD." The opening- 0 of' th'e' ratchet-head isv particularly adapted toreceive the reduced; squared end pof 'a removable socket P. It willibeunderstood that the bodies of'these sockets P are of varying sizes,while theirshank's onends p are substantiallyuniform in size.

To facilitate the retention o f"the socket end, particularly in case ofslight variations -.of dimensions,'the head 0 is recessed longitudinallythe opening -0 8 81 at Q, and in its-adjacent front and rear sides, asat g, and a fiat spring 9' applied to the recess Q; the

ends g ofrthe spring being bent at substantially right angles to thespring. These ends form ears provided with teats 9 adapted to enter therecesses q whereby the spring is assisted in retaining its positionrelatively to the slot or recess Q. "The spring normally extendingoutwardly from the surface of the head 0 to frictionally engagethe endof the socket; Adjacentithe head 0 is a pin R whose squared reduced endsrenter the openings g and g of the plates of the head, and upon this pinis pivotally mounted a pawl S provided upon its rear withtwo interspacedshoulders s and upon its forward margin with twointerspaced teeth 8'adapted to alternately register intermediate the teeth o when the pawlis rocked. In broke'n lines is shown a second position of the pawl asrocked.

In the portion of the head adjacent the handle is located transversely aplate T whose reduced ends t enter openings t and t in the plates C andD respectively. This Passing loosely through the'opening if is a shankportion u of a lever U having an enlarged head to provided with apointedend u. A spring a surrounds the shank u and has one end bearingagainst the plate T and its other end against the head u" of the lever.The portion u of the lever is provided with a longitudinal slot uhWashers 11 are located at each side of the head. A pin V passes looselythrough the washers and the openings k h and a and has upon its oppositeends knurled heads '0, so that by the thumb and finger the lever U maybe transversely vibrated from the position shown in full linesvin Fig. 2to the position shownin broken lines therein, thus reserving therelative position of the teeth 8' with relation to the teeth 0 on theratchet head.-.

It will be observed that by vibrating the handle one of the teeth 8 willengage and rotate the-ratchet head in one direction only,

while when the other tooth s of the pawl has been shifted into contactwith the ratchet teeth by means of the lever U the ratchet head Wlll beimpelled in the opposite direction at each reciprocation of the handle.It will be further observed that all the operating parts are inclosedWithin the housing formed by the plates C and D and their respectiveflanges, and that the assemblage of the parts is firm, simple, and freefrom the use of solder, and that the resulting structure iscomparatively light.

I claim 1. In a ratchet wrench, a head portion having a rigid handle, aratchethead rotatably mounted in hearings in said head portion andhaving socket opening and pe ripheral teeth, a pawl pivotally mounted inthe head portion for rocking movement and having interspaced shoulders,a bodily movable lever having a longitudinal slot, a spring around theshank of said lever, a guide for said shank against which said springhas a bearing, the head portion bein provided with transverse openingsan transverse depressed portions thereto and a pin passed loosely trough said 0 enings and through the longitudinal slot 0 the lever andhaving heads dis osed in said depressions for transversely v1 ratingsaid lever.

2. In a ratchet wrench, a head portion having a rigid handle, a ratchethead rotatably mounted in bearings in said head portion and havingsocket opening and peripheral teeth, a pawl pivotally mounted in thehead portion for rocking movement and having interspaced shoulders, abodily movable lever having a longitudinal slot, a spring around theshank of said lever, a guide for said shankagainst which said spring hasa bearing, the head portion being provided with transverse openings anda pin passed loosely throu h said openings and through the longitu inalslot of the lever, and washers on said pin upon opposite sides of saidlever.

In testimony whereof Ihave afiixed, my signature in presence of twowitnesses.
